I-preamplifier (preamp) iyi-electronic isikhulumi elungiselela isignali encane kagesi ukuze ikhulise noma icutshungulwe.
I-preamplifier ivamise ukubekwa eduze kwenzwa ukuze kwehliswe imithelela yomsindo nokuphazamiseka. Isetshenziselwa ukukhulisa amandla esignali ukushayela ikhebula ethuluzini eliyinhloko ngaphandle kokwehlisa kakhulu isilinganiso se-signal-to-noise (SNR).
Ukusebenza komsindo kwe-preamplifier kubalulekile; ngokwefomula kaFris, lapho i inzuzo ye-preamplifier iphezulu, i-SNR yesiginali yokugcina inqunywa i-SNR yesiginali yokufaka kanye nesibalo somsindo we-preamplifier.
Kusistimu yomsindo wasekhaya, igama elithi 'preamplifier' ngezinye izikhathi lingase lisetshenziswe ukuchaza okokusebenza okumane kushintshe phakathi kwemithombo yeleveli yolayini ehlukene futhi kusebenzisa isilawuli sevolumu, ukuze kungabi bikho ukukhulisa kwangempela okungabandakanyeka.
Kusistimu yomsindo, iamplifier yesibili ngokuvamile iyisikhulisamandla samandla (i-amp yamandla). I-preamplifier ihlinzeka ngokuzuza kwamandla kagesi (isb. ukusuka kumamilivolthi angu-10 ukuya ku-volt engu-1) kodwa akukho nzuzo enkulu yamanje.
I-amplifier yamandla ihlinzeka ngokwamanje okuphezulu okudingekayo ukuze ushayele izipikha.
Izithuthukisi zingase zibe: zifakwe endlini noma ku-chassis yeamplifier ezifunzayo endlini ehlukile efakwe ngaphakathi noma eduze nomthombo wesignali, njenge-turntable, imakrofoni noma insimbi yomculo.
Izinhlobo ze-Preamplifier: Izinhlobo ezintathu eziyisisekelo zama-preamplifier ziyatholakala: i-preamplifier ezwela manje, i-parasitic-capacitance preamplifier, kanye ne-preamplifier ezwela ukushajwa.
NginguJoost Nusselder, umsunguli we-Neaera kanye nomkhangisi wokuqukethwe, ubaba, futhi ngiyathanda ukuzama izinto ezintsha ngesiginci enhliziyweni yesifiso sami, futhi kanye nethimba lami, bengilokhu ngidala izindatshana zebhulogi ezijulile kusukela ngo-2020. ukusiza abafundi abathembekile ngokurekhoda namathiphu esiginci.
